To @ZZ whom it may concern:

Be it known that I, SHELDON J. GLASS, a citizen of the United States,and a resident of Milwaukee, in the county of Milwaukee and `State ofWisconsin, have invented certain new and useful Improvements inCoin-Boxes for Coin-Controlled Mechanism; and I do hereby declare thatthe following is a full, clear, and exact description thereof.

My invention relates to'coin-boxes for coincontrolled mechanism; and itconsists in certain peculiarities of construction and combination ofparts, as will be fully set forth hereinafter and subsequently claimed.

In the drawings, Figure 1 is a central vertical longitudinal sectionalview of my device on the line 1 l of Fig. 2.v Fig. 2 is a centralvertical transverse sectional view of the same on the line 2 2 of Fig.l. Figs. 3 and 4 are sectional views on the same line as in Fig. 2, butwith the movable parts in different positions. Figs. 5 'and6 are endviews of the dev1ce.

Referring to the drawings, A represents a block of any suitable metalwith a straightwalled vertical opening therethrough of a size justsuflicient for the passage of a coin of predetermined size, saidyopening being herein termed the coin-slot B. Further, the said block isformed with two longitudinally-disposed cylindrical bores extending fromone end almost to the opposite or outer end and arranged one above theother to receive the hereinafter-described cylinders, and the said outerend being formed with bores of lesser diameter to receive the outertrunnions or journals of said cylinders. These cylindrical boresintersect the described coin-slot B, and the walls of said coin-slot arepreferably enlarged, or ared, or beveled outwardly at said points ofintersection. A

D is the upper cylinder, preferably solid, save for a longitudinal slota cut therein and extending nearly but not quite through said cylinder,this slot ot corresponding in dimensions to the described coin-slot B inthe block A and. exactly registering therewith when the said cylinder DisV in the position shown in Figs. l and 2, with the opening of the slota, uppermost to receive a coin E or when said cylinder'has made ahalf-revolution to discharge the coin therefrom, as shown in Fig. 3.

C is a plate secured to the inner end of the block A, as by screws b b,and formed with bores therethrough for the trunnions of the cylinders,the upper bore in said plate receiving the trunnion c of theV cylinderD, While the trunnion d of said cylinder projects through the upper borein the outer end of the block A and there receives a disk F, whoseperiphery or segment thereof isformed with teeth to mesh with the liketeeth on alower disk G, hereinafter described. The disk F is formed or`provided with stops e f for engagement with like stops g h on the lowerdisk G, as4 hereinafter described. In the construction illustrated inthe drawings these stops consist of the straight parallel upper andlower ends of metallic pieces rigidly secured to the disks F G, it beingonly essential that each of these disks F G should carry therewithprojections adapted to come into contact v at the half-revolution ofsaid disks in either direction and thereby prevent the further movementof said disks in that direction. In Fig. 6 the stop or projection e ondisk F is in contact with the stop or projection g on disk G, and whenthe said disks F G are turned in the opposite direction (by thehandwheel j).the stopor projection f on disk F will come in contact withthe stop or projection h on disk G 'and thereby stop the movement ofsaiddisks in that direction at a halfrevolution thereof.

The lowercylindrical bore in the block A is for the reception of thedouble concentric coin-shells H I, nested together, as best shown inFig. l. The head of the coin-shell H is provided with a shaft c',extending through the lower bore in the outer end of the block A,and-having secured to it the described disk G, beyond which said shaftcarries a handwheel j, while the inner face of the head of said shell His formed with a'conical concave seat k.

fm is the outer and n the inner shell y of the said coin-shell H, theshell m resting on an annular shoulder on the inner side of the head ofthe coin-shell I, which latter part has also an outer shell o,projecting between the shells m and n of the other part, and a shell pwithin the said shell n, when the two IOO parts II and I are nestedtogether, as shown and described. Further, the part I has aninwardly-projecting shaft q, terminating in a pointed conical end o',fitting within the described conical seat L in thehead of the part H,while from the outer side of the head of the part I there projects ajournal or shaft s, extending through the lower bore in the plate C,beyond which said shaft carries a ratchetwheel J.

K is a spring-paul secured to the plate C and in engagement with theratchet-wheel J, and L is a pin ou said plate C, against which the saidpawl K bears.

M is a top plate of hardened steel, secured to the block A in anysuitable manner, as by screws t t, and formed with a slot utherethrough, which slot exactly registers with the described coin-slotB. It will be understood that the said block A is designed to be securedin a suitable casing, so that the screws herein shown will not beexposed but will be wholly covered up, as will be the described disks orsegments F G and ratchet-wheel .I

u and pawl K, all as indicated by the double dotted lines in Fig. l, andthat a proper receptacle is provided in said casing below the bottom ofthe block A for the coins from the slot B to drop into, and that saidreceptacle is to be provided with a proper locked door; but as suchcasing, coin-receptacle,and locked door are common to all devices ofthis kind and form no part of my present invention I have not deemed itnecessary to illustrate the same.

All of the concentric shells of the parts II I are formed with slotstherethrough, there being only one slotin the outer shell m of the partH and two registering slots through the inner shell n. The shells o pand central shaft q of the part I are all provided with slotsregistering with each other, and these slots in the part I are broughtin line with the described slots in the part H only when the:

stops on the disks F G are in engagement.

The operation of my device will be readily understood from the foregoingdescription of its construction, taken in connection with theaccompanying drawings. As is well known, the class of apparatus to whichdevices such as I have described are particularly applicable embracesuch as are designed to contain or control a supply of vendible articlesor material as well as such as have movable parts adapted to be set inmotion or to have their movements controlled or regulated, or saidmovable parts released or permitted to be set in motion by means of acoin of predetermined dimensions dropped into the coinbox, and hence itis desirable that such coinbox should be so constructed as to preventany tampering with the same or the withdrawal of any coin depositedtherein or any access to the operating devices save by the properdeposit of the required coin, and these objects are attained by myconstruction, the operation being as follows: The hand-wheel j is turnedto bring the parts into the relative positions shown in Figs. l, 2, andG, this being accomplished by the movement of the intermeshing tootheddisks or segments F G until such movement is stopped at the end of ahalf-revolution bythe engagement of the stops c g. A coin E of theproper size is then dropped through the slot u in the top plate M andthe upper part of the coin-slot B into the slot a in the cylinder D, allof these slots being in register, as shown, and the said Coin being heldwithin the slot in the said cylinder D by reason of the said slotextending only partly through said cylinder. rIhe hand-wheelj is thenturned a half-revolution in the reverse direction until its movement isstopped by the engagement of the stops f L on the toothed disks orsegments F G, and this movement of the intermeshed disks or segments hasserved to bring the cylinder D and the cylindrical coin-shells II I intothe relative positions shown in Fig. 3, when the coin E will drop out ofthe slot a in the cylinder D, pass through the central portion of thecoin-slot B, and fall into the slot in the coin-shells II I, being heldtherein by reason of the then lower edge of said coin being in contactwith the unslotted portion of the outer shell m of the part II. It isnow impossible to withdraw said coin, because the solid or unslottedpart of the cylinder D effectually closes the passage or coin-slotleading downward from the top slot u, and, further, until the coin isreceived within the slot in the parts H I there can be no operation ofthe apparatus to which my device is connected, as the mechanism which isto be set in motion is connected to the shaft s on the part I, and theshells m n of the part II move freely within and about the shells o p ofthe part I as the hand-wheelj is turned back and forth until the coindrops into the described slotted passage in said parts II I. The momentthis is done the said parts H I are locked together by the coin, andthen as the handwheelj is again reversed and moved in thefirst-described direction the parts D and II I are again brought intothe relative positions shown in Fig. 2 and the coin drops out throughthe lower end of the coin-slot l5 into the receptacle below, and byreason of this interlocking of the parts II and I by the said coin thepart I moves, thereby revolving its shaft s and actuating, releasing, orotherwise controlling the mechanism connected to said shaft s, whateverit may be.

The part A, which I term the block,77 need not necessarily be all of onepiece, but may be more conveniently formed of two pieces, as thehardened steel top plate M will guard against any tampering with saidpart A and its contained cylinder D, and there can be no object inwithdrawing a coin from the cylinder D when the latter and coin are inthe relative positions shown in Fig. 2, as no operation of the devicecan take place until the coin has been dropped into the posi- IOC) IIO

tion shown in Fig. 3, beyond recovery, and the partsII I interlocked,asalready described.

It is essential to the proper and consecutive working of'my device thatthe part I of the coin-shells shall always stop at the conclusion ofeach half-,revolution with .its described slots in perfect line orregister with the coin-slot B in the block A, as otherwise itwould beimpossible for the next coin from the cylinder D to drop into the saidcoinshells, and this result is secured by the described Vratchet-wheel Jand pawl K, which prevents any backward motion and the teeth of saidratchet-wheel being cut, so that the pawl will-hold the saidratchet-wheel and the shaft s, to which it is secured, and the coinshellI, which is rigid with said shaft, stationary at the precise pointnamed, when the stop on the disk or segment G engages with the stop onlthe other disk or segment F, and so` long as this is accomplished theprecise nature of the detent which thus holds the coinshell I againstmovement is immaterial; but Ihave found the described pawl and ratchetto work admirably in practice.

Having thus described my invention,what I claim as new, and desire tosecure by Letters Patent, is-

1. In a coin-box for coin-controlled mechanism, the combination with ablock having a vertical-coin-slot therethrough and cylindrical boresintersecting said coin-slot, and arranged one above the other, of acylinder in the upper bore having a slot extending partly therethroughand adapted to be brought into register with said coin-slot, and a pairof double concentric coin -shells, nested together y within the lowerbore and provided with slots extending entirely through all the shellsbut one, said slots being adapted to be brought into register with eachother and with said coin-slot, and the upper cylinder and coinshellsbeing so connected together that when the former is in position toreceive a coin the slotted passage between them is closed, andl whensaid coin has been dropped into the coinshells, the passage from the topof the block to the slot inv said upper cylinder is closed.
